Abstract
A high characteristic temperature with To of 126K under continuous-wave ope ration is obtained for an InAs/GaAs quantum dot laser. A triple-stacked act ive region with an energy separation of 95meV between the ground and first excited radiative transitions is used to achieve a ground state saturation gain at 300K of 13cm(-1), and high internal quantum efficiency of 74%.
